T0 aZZ whom it may concern:

Be it known that I, SAMUEL HOW'ARD SroTT, a subject of the Queen ofGreat Britain and Ireland, residing at Fulwood, Preston, in the countyof Lancaster, England, have invented Improvements in Means forImpregnating the Water or Liquid Discharged from Syringes, (for which Ihave obtained a patent in England, No. 6,769, dated May 2, 1890; inVictoria, No. 8,330, dated December 10, 1890; in New South Wales, No.2,765, dated December 12, 1890; in New Zealand, No. 4,7 89, datedJanuary 6, 1891; in France, No. 211,060, dated January 29, 1891; inBelgium, No. 93,601, dated January 30, 1891; in Germany, February 1,1891, and in Italy, LVII, 66, dated March 31, 1891,) of which thefollowing is a specification.

This invention has for its object to provide means for impregnating thewater or liquid discharged from the outlet end or nozzle of a syringe,with substances soluble in water such as those used forinsect-destroying, fertilizing, and deodorizing purposes, and itconsists in interposing between the outlet end of the cylinder or pumpbarrel of the syringe, and the nozzle or spray-producing device, achamber arranged preferably in line with the cylinder. The ends of thechamber are made of sheet metal perforated with a number of small holes,and the chamber may conveniently be made to screw on to the outlet endof the cylinder, and to have the nozzle or spray-producing devicescrewed on to its outer end.

In the accompanying drawings, Figure 1 shows partly in side elevationand partly in longitudinal section diffusing apparatus con- Figs. 2 and3 are detail views to a larger scale hereinafter referred to.

1 is the pump barrel of an ordinary form of garden syringe to the outletor discharge end of which is screwed a casing 2 that forms a mixingchamber 2 to hold the fertilizing, insect destroying, or otheringredient. The two ends of this chamber are each made of a sheet 3 offine wire gauze and a perforated plate 4: that serves to support thegauze while water is being forced through the chamber. The sheets ofgauze and their supporting-plates may be held in place as shown, onesheet of gauze and its plate being placed between the pump barrel 1 andthe casing 2, and the other sheet and plate between this casing and itsremovable cap or cover 2 In Figs. 2 and 3, which are respectively a faceview, and a central section, one of these sheets of wire gauze with itssupporting plate is shown detached from the apparatus. The water orother liquid sucked into the pump barrel when the piston 5 is drawn tothe inner end of its stroke by the handle 6, may enter through a hole 7in the cap or cover 2", and through a cage 8 provided with a sphericalor ball valve 9; and as it passes through the mixing chamber, it becomesimpregnated with the material therein. When the water or other liquid isforced out or discharged from the pump barrel by the piston, it will onits return passage through the chamber 2 become still further mixed withthe impregnating material, and be discharged through a nozzle 10, thevalve 9 at this time being closed against its seat in the cap 2 so as toclose the hole 7. If the casing 2 be permanently secured to the pumpbarrel, it may be charged with the desired material through an openingor openings formed in its side and normally closed by a screw cap orcaps. When however it is made removable from the pump barrel as in theconstruction described and shown it may be simply removed from the pumpbarrel for charging, or the cap or'cover 2 may be removed from thecasing for this purpose.

Although I prefer to employ in conjunction with a syringe having amixing chamber as above described a nozzle 10 of the kind described andshown in the specification of another application for Letters Patentfiled byme dated August 25, 1891, Serial No. 158, 133, and in which theissuing water is caused to meet an obstructing medium such as the underside of a cap 11, any of the ordinary forms of nozzle or rose may be soemployed.

What I claim is:

1. In a syringe, the combination of the bar-.

ends of the barrel and casing, the cap screwed on the outer end of saidcasing, the perforated plate and gauze clamped between the end of saidcasing and said cap, said cap provided with a nozzle and a valved inlet,substantially as described.

2. In a syringe, the combination of a barrel having a piston and anextended end to contain insect destroying or like substance, a cap onsaid end provided with a discharge nozzle and an inlet opening, a ballvalve to close said opening against outflow and a chamber for saidvalve.

3. In a syringe, the combination of the barrel 1, the piston 5, thechamber or casing 2 on the end of the barrel provided with, theperforated ends 3, 4, the cap or cover 2 on the outer end of said casing provided with an outlet and with an inlet opening controlled by thevalve 9 substantially as described.

4. In a syringe the combination of the barrel 1, piston 5, chamber orcasing 2, on the end of the barrel provided with the perforated ends 3,4, and having cap 2 provided with a discharge nozzle 10, and an inlet 7,a cage 8 in said cap and a ball valve in said cage to close said inletagainst outflow.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
